Introducing the Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M36x4, a purpose-built tapping solution engineered for dependable, high-precision threads in a variety of metals. Crafted from high-speed steel and ground for exact pitch and flute geometry, this uncoated tap is ready for demanding workshop use and everyday fabrication alike.

• Two-start (second lead) design — accelerates threading by pairing two cutting starts with a single pitch. This arrangement reduces the turning force required and speeds up hole threading without sacrificing thread accuracy.
• Metric M36x4 threads with ISO 529 dimensional control — ensures clean, wear-resistant threads that pair seamlessly with standard metric nuts and bolts.
• Right-hand thread — the conventional cutting direction for most steel, cast iron, and aluminum applications, delivering predictable results with clockwise rotation.
• High-speed steel, ground finish for crisp, uniform flanks and consistent thread depth across the length of the tap.
• Uncoated, general purpose — a versatile tool suitable for a broad range of metals and common tapping tasks in home workshops and professional shops alike.
• Optimized for efficiency Designed to deliver strong thread engagement quickly, reducing cycle times in production runs and enabling faster prototyping and repairs.

What makes this Wiseman tap stand out

Compared to standard single-lead taps, the second-lead configuration distributes cutting action across multiple starts. This results in smoother chip evacuation, less burr formation, and steadier hole quality—especially valuable for deeper or longer-threaded holes. The combination of M36x4 sizing, ISO 529 conformity, and a robust HSS composition provides a reliable, long-lasting tool that you can count on for consistent results across projects.

Ideal use cases

Machinists, metalworkers, and DIY enthusiasts will find this tap especially effective for:

• Creating strong, ripple-free threads in steel, iron, and aluminum parts
• Repairing or fabricating components where metric fasteners require precise M36x4 threads
• Through-hole and blind-hole projects in general metal fabrication, machinery housings, and framework assemblies

Practical tips for best results

• Lubricate with appropriate cutting oil to reduce heat and extend tap life.
• Use steady, even pressure and maintain a consistent feed to maximize thread quality.
• Start with a pilot hole sized per typical metric guidelines, then progress to the full M36x4 tap as you cut deeper.
• Clean the hole and tap occasionally to clear chips and prevent binding.

The Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M36x4 is a reliable, high-performance choice for anyone who values speed, precision, and durability in metalworking threads. Built to handle a range of materials and applications, it’s the workhorse tap you’ll reach for again and again.
